6PPD Exposure and Effects Research at Columbia Environmental Research Center

N-(1,3-dimethylbutyl)-N' -phenyl-p-phenylenediamine or 6PPD is a chemical additive that protects tires from damage due to certain reactive oxygen species. 6PPD, when in contact with ozone, reacts to form the derivative 6PPD-quinone (6PPD-Q). As tires wear with time, this derivative is dispensed into the environment, travels through drainage systems when it rains and, eventually, finds its way into...

A National Assessment of Pesticide, PFAS, Microplastic, and Antibiotic Resistance Gene Exposures in White-Tailed Deer

Research has documented exposures and consequential environmental health effects of pesticides, PFAS, microplastics, and antibiotic resistance genes in environmental biota. Little is known, however, regarding such effects in white-tailed deer ( Odocoileus virginianus ).
